Swap the...:
arctic silver 5 for mx3, or the IC7 diamond stuff sold on this website
haf922 for either a fractal define or cm690 II
samsung f3 for a WD Black 1tb 64mb cache (make sure it's the 64mb version)
tx750 for a hx650
hyper 212+ for a venomous X

The 460 is a good choice, but personally I don't like it because it's short and looks ugly in a big case. If your budget allows, get a gtx470, much bigger and beefier and looks better :)

What would "this" website be just to clarify? I'd like to check out prices.
